摘　　要：苹果酸是植物体内参与C4循环、景天酸循环等众多代谢途径的关键代谢物。苹果酸含量提高的途径主要来自植物体内合成的提高。苹果酸脱氢酶(MDH)可引起草酰乙酸盐的氧化作用以形成苹果酸盐,增加植物体内苹果酸的含量,从而显著提高植物体的耐酸性以及对铝毒的抗性。本文全面回顾了国内外对苹果酸脱氢酶(MDH)在植物生理学、生物化学、分子生物学、系统分化领域的研究进展,并针对其在植物体耐酸性机制机理研究领域所取得的研究成果进行了追溯。As a key metabolic compound, Malate dehydrogenase plays a key role in many chemical reactions such as C4 pathway and crassulacean acid metabolism. It can catalyze oxaloacetic oxidation to reverse into malate therefore yield to malate increase within plants, which will definitely increase plant acid resistance and aluminum toxicity tolerance. Progress of Malate dehydrogenase in plant physiology, biochemistry, molecular biology and phylogenetic research fields both abroad and at home together with research achievements of whose functiom in plant acid-resistance methods and principles are traced back exhaustively in this article with expectation to highlight acid-resistant alfalfa selection and germplasmic improvement.
